Modifies provisions relating to the collateral source rule

This bill modifies how courts handle medical cost evidence in personal injury cases, directly affecting plaintiffs, defendants, and their insurance companies. It clarifies that if a defendant or their insurer pays for a plaintiff's medical bills before a trial, that defendant cannot be charged again for those same costs during the lawsuit. The law also defines "actual cost" as the amount a patient actually pays or owes after discounts and write-offs, rather than the original bill amount, and allows this adjusted figure to be used as evidence for estimating future medical needs. By removing the ability to introduce inflated billed amounts, the legislation aims to prevent double recovery for medical expenses while maintaining the admissibility of relevant cost data.
